People tend to check in during these times:
In the winter, the tracks create a pretty strong wind tunnel by the east stairs so, unless you're really bundled up, wait for the train a little further in on the platform.
the new automated kiosk machines for purchasing tickets are sluggish and slow; give yourself time to get in line as the lines move very slowly
Trains on time except when there's something wrong with the track or there's something in the way
After a long but quick walk from George Brown to Union I welcome the wind that blows on the platform!
